We adapted a spin-echo center-out echo planar imaging with
ultra-short echo time [TE] (DEPICTING) pulse sequence with an inversion
recovery [IR] preparation.Two series
of 32 pseudo-randomized TIs were acquired with two TEs and analyzed by
cross-regularized inverse Laplace transform.The human white matter water proton T2 value associated with the short
component w. small water proton T1 detected by IR relaxographic analysis was
determined to be 34.2 ms and supports its the assignment as a myelin water
fraction.
